UNITED STATES BOOK COVER Francis John Osuch, Detroit, Mich. ApplicationApril 24, 1933, Serial No. 667,521

6 Claims.

The present invention relates to a novel book cover adapted to beapplied to a bound volume, such as a directory, or for enclosing loosesheets of paper, and more particularly to a device for supporting atelephone directory by means of index sheets, such as shown in my priorPatent No. 1,900,462, issued March '7, 1933.

The primary object of the present invention is to provide a sturdy andattractive cover that may be readily applied to bound volumes in amanner permitting its use repeatedly on successive edi-l tions. In thisconnection the invention provides bowed rods, similar to those shown inmy prior Patent No. 1,900,462, wherein index sheets are provided withapertured tabs through which the bowed rods extend to secure the sheets.within the cover in which the bowed rods are secured, these indexsheets being the means of securing a bound volume within the covers. norder to facilitate easy removal of such bowed rods and to permit thesame covers within which they are secured to be applied quickly andeasily to another volume, the present invention provides a novel meansfor securing such bowed rods within the covers, and such meansconstitutes an improvernent over the above mentioned patent.

With the above and other ends in View the invention consists in mattershereinafter set forth and more particularly pointed out in the appendedclaims, reference being had to the accompanying drawing, in which-Figure 1 is a plan view of the present cover in an open position;

Fig. 2 is an end View corresponding to Figure 1;

Fig. 3 is a fragmentary cross section taken along the line 3-3 of Figure1;

Fig. 4 is an enlarged fragmentary plan with parts broken away;

Fig. 5 is a fragmentary side elevation;

Fig. 6 is a perspective view of an angle bracket, and

Fig. 7 is a perspective view of a locking plate.

Like characters of reference are employed throughout to designatecorresponding parts.

The present cover comprises a central back piece 1 and sides or flaps 2hingedly attached to the longitudinal edges thereof, or as illustratedthe back and flaps may be constructed as a single integral part that iscreased as at 3 to provide the hinge or bending action at the desiredpoint.

The back strip 1 is somewhat wider and longer than the back or bindingof a book or volume or a plurality of books or volumes to be receivedwithin the covers.

'" To each of the ends of the back strip 1 is secured an angle bracket 4that extends transversely thereof and is secured thereto by hollowrivets', i the upper ends of the rivets being counter-sunk." as at 6 incounter bores in the upper `surfacefof the bracket so that said uppersurface remains smooth. The bracket 4 is formed with an integral finger7 projecting upwardly from one end theref oi" and bent to lie in aplaneparallel to vand spaced from the bracket 4. On the same end of thebracket 4 as the nger 7 is formed an upwardly directed ange 8, andadjacent the other'end is formed another iinger 9 that corresponds inshape, size and spacing to the finger '7. The hol low rivets 5 arelocated adjacent the ends of the bracket 4 and apertures are formed inthe4 fingers 'Z andL 9 and are each directly in line with one of 'thehollow rivets.I

A bowed rod 11 is provided with grooves 12 adjacent its ends and theends"y of the rod are inserted through the apertures 10 in the fingers 7and 9 and enter the hollow rivets 5. A guide nger 13 is secured on thebracket`4and serves to hold vthe bowed rod 13 ina position whererthe.grooves 12 are located in the space between ythe ngers 7 and 9 and thebracket 4. The bowed rod ll may be formed of one continuous piece, or itmay be formed of two pieces, one having a bore and the other havingafpilot portion inserted therein as at 1.4, the objecty in forming it intwo parts not being to alter the function thereof but to permit easyinsertion of the rod through perforations in a large number of sheets ofpaper at one time.

A locking plate 15 has one end received beneath the finger '7, and aslot 16 in that end in which the groove 12 on the rod which is locatedbetween the nger 7 and bracket 3 as above described is received.Adjacent the other end the locking plate is provided with a keyhole slot17 that permits the plate to lie flat on the bracket 4 so that thereduced portion of said keyhole slot may receive the groove 12 in theend of the rod that projects through the nger 9. The locking plate 15 isprovided with an upturned flange 18 that serves as a nger piece so thatpressure may be applied thereto manually to slide the locking plate onthe bracket 4 beneath the fingers 7 and 9.

It is obvious that books, sheets, or folders having apertures therein orapertured tabs thereon, may be assembled on the rods 11 which then havetheir ends inserted through the fingers 'I and 9 so that they enter therivets 5, with the grooves 12 in the rods located betweeen the fingersand the brackets. The locking plates 15 are then moved soA rtf-

loo

i rods 11 the brackets'fi are provided with depressions or grooves 19into which the ends of springlike flexible rods 20 are inserted bybending the same. Y

Although a specic embodiment of the present.

invention has been illustrated and described,l it is to be understoodthat various changes may be made Within the scope of the`appendedclaims, without departing from the spirit of the invention, andsuch changes are contemplated What I claim is:

1. A vdevice of the character described including a brackethaving/spaced apertured members formedk integral therewith, asubstantially U- shaped grooved member having its ends inserted vthroughthe apertures in said spaced members withl the groovetherein locatedbetween said bracket and'said spaced members, and a locking platehavinga keyhole slot surrounding one of said spaced members and slidablebeneath the other of said members, said looking plate. having portionsreceived in said grooves and preventing withdrawal of said U-shapedgrooved member from said apertures.'

2. A book cover including a back strip, a bracket secured to said backstrip, said bracket having an aperture therein, an apertured memberspaced from said bracket abovejthe aperture in said bracket, Aa rodextending through said apertured member into the'aperture in saidbracket, said rod having a groove disposed between said bracketan'daperturedmember, and a locking plate having a keyhole slot surroundingsaid apertured member and facilitating reception of said plate inA thegroove in said rod.`

3. A book cover comprising a back strip, brackets secured adjacent theends of said back strip, each of said brackets having a pair ofapertures formed therein, fingers spaced above said brackets andprovided withV apertures, said iingers corresponding in number to theapertures in said brackets, rods having grooved ends extending throughthe apertures in said fingers into the apertures in said brackets, and alocking plate on each bracket, each locking plate having a keyhole slo-tpermitting movement thereof between one of said fingers and itsrespective bracket and entering said groove in the end of said rod whichis disposed between said respective. iinger and bracket. v

4. A book cover comprising a back strip, brackets secured adjacent tothe ends of said back strip, saidbrackets each having a pair of`apertures therein, a pair of fingers spaced above each of saidl bracketsand provided with apertures, a substantially U-shaped rod having groovedends extending" through said ngers into the apertures in eachk bracket,locking plates, each of said lockingl plates yhaving relieved portionspermitting movement thereof between said iingers and their respectivebrackets and enteringA said grooves in the ends of respectiverod's,`said bracketshaving depressions therein, and flexible rods havingop" posite ends received insaiddepres'sions in ,opposite brackets.v

5. A book'. cover comprising 'a back 'stripifa' bracket, hollow rivetssecuring said bracketadjacent to the end of said back strip, iingersspaced above said Ibracket and having apertures in line` a back strip, apair ics of brackets, hollow rivets securing said brackets adjacent tothe ends of said back strip, a pair of fingers spaced above each bracketand having` apertures in vline with said" hollow rivets, a groovedrodinserted'through each pair of said fingers and entering` said'hollowrivets on respective brackets, a'locking plateA 'oneach'bracket havingrelieved portions permitting movement thereof between each bracket'andits respective lingers to enter said grooves in saidrrods, saidbrackets' having elongated depressions formed therein', and flexible'rods having their opposite endsreceived in depressions in oppositebrackets.
